The NHL was not about to do something as radical as Major League Baseball and grant home-ice advantage for the Stanley Cup Final based on an All-Star result, but on Sunday it will unveil its own outside-the-box solution.

Rather than anything resembling an actual game, the league will hold a three-on-three tournament consisting of three periods played entirely with three skaters a side.

The Atlantic Division will face the Metropolitan and the Central will meet the Pacific — with the order to be determined based on Saturday night’s skills competition — and the winners will play for the championship and a $1-million championship pot.

Goalies are less than ecstatic about the idea, but All-Star Games always have been long days at the office for them. The skaters mostly have embraced it.

“There’s more ice and I think fans want to see players play a little harder, try a little harder,” Flyers captain Claude Giroux said. “Guys obviously don’t want to get hurt, and in three-on-three, you can go a little harder and you know there are not going to be a lot of hits and your percentage of getting hurt is not as high.”

The three-on-three idea grew out of this season’s change in regular-season overtime rules, in which rather than going four-on-four for five minutes, teams play three-on-three. It has been a hit with fans and reduced the number of shootouts needed to decide games. (A shootout will be used Sunday if a minigame ends in a tie.)

Naturally, the fastest skaters are the most excited about Sunday’s action. Less so is soon-to-turn 44-year-old Jaromir Jagr of the Panthers.

“I don’t think I’m going to play much three-on-three,” he said. “I don’t play it much in Florida and we have the same coach here [in Gerard Gallant]. This time I won’t mind.”

All eyes will be on how Pacific Division captain John Scott, a 6-8, 260-pounder who initially was elected by fans as a joke candidate, handles all that open ice — and how fans greet him.

“I hope the fans cheer and they’ll take it for what it is,” he said. “It’s obviously an anomaly. I’m not the typical All-Star, and it’s probably not going to happen again.”

McDonagh, a defenseman, laughed when pondering the notion of filling his customary role trying to prevent scores. “There will be plenty of highlight-reel goals, I’m assuming,” he said.

The Islanders’ John Tavares scored four goals in last year’s All-Star Game in Columbus and figures to be a key force for the Metropolitan. But no one knows exactly what to expect.

“It will be different,” he said. “I’m sure it’ll be similar to old All-Star Games where you’ll see early a feeling-out process. But I’m sure as the game picks up and the game’s close, guys will pick up the intensity and play and obviously try and put on a good show.

“It should be entertaining.”

That’s the idea.
